Window 11: 11,12,13 = 2+3.5+2.5=8. \u2713.\n\nBut wait, need to check greedy: sorted by score desc. Let's list top candidates. Window 6-9=12. Window 29-32=10. Then next highest... window 30-33? hour 33 null, skip. Window 7-10 = 3+4+2=9. Window 28-31=1+3+2=6. Window 11-14=8. Window 12-15=3.5+2.5+0=6. Window 31-34: hour33 null skip. Window 5-8= -1+5+3=7.

Window 44-47=2+1+null skip. Window 42-45=-1+3+2=4. Window 3-6=-1-1+0=-2. \n\nSo sorted: 12(6), 10(29), 9(7), 8(11), 8(8), 7.5(10), 7(5), 6(9), 6(12), 6(28), 6(37)...\n\nGreedy: keep 6-9. Next 29-32 (no overlap) keep. Next 7-10 overlaps 6-9 skip. Next 8-11 overlaps skip. Next 10-13 no overlap with 6-9 (10>=9) and no overlap with 29-32 -> keep. So third window is 10-13 with score 7.5, not 11-14 with 8!\n\nWait, my code gave 11-14 with score 8. Let me recheck. Sorted by score desc then start asc. 8(11) comes before 8(8) and before 7.5(10). So order: 12(6), 10(29), 9(7), 8(8), 8(11), 7.5(10)...\n\nWait sort key is (-score, start). So among score 8: start 8 and start 11. 8 comes first. So order: 12(6), 10(29), 9(7), 8(8), 8(11), 7.5(10).\n\nGreedy: keep 6-9. 29-32 keep. 7-10 overlaps 6-9 skip. 8-11 overlaps 6-9 skip. 11-14: no overlap with 6-9 (11>=9) and no overlap 29-32 -> keep. So 11-14 score 8. \n\nI made an error earlier: 8(8) is window start 8, not 11. Let me redo. Window start 8 = hours 8,9,10 = 4+2+2=8. Window start 11 = hours 11,12,13 = 2+3.5+2.5=8. Both 8. Start 8 first. 8-11 overlaps 6-9 (8<9). skip. Then 11-14 keep. Yes correct. Good, code output matches.\n\nNow let me double check the daylight for day1: sunrise 5, sunset 18. h=24 -> hour_of_day 0, outside -> -2. h=24 score: wind 4.2, major? [19.15,21.15] no, [31.55..] no. minor? [25.35,26.35] no. tide d=|0.72-1.17|=0.45 -> +2. wind<=10 no penalty. dp=pressure[24]-pressure[21]=1008.1-1007.9=0.2 -> no. daylight outside -> -2. total=0. \u2713\n\nh=25: wind 0.6. major no. minor [25.35,26.35] overlaps [25,26)? 25.35<26 and 26.35>25 yes -> +1.5. tide d=|0.46-0.72|=0.26 -> +1. dp=pressure[25]-pressure[22]=1007.7-1008.0=-0.3 no. outside daylight -2. total=1.5+1-2=0.5. \u2713\n\nGood.\n\nNow the SVG. Let me check it's valid and static. Let me view it.\n\nAlso I should clean up the unused compute_windows function. Let me remove it.\n\nLet me check the SVG output."
